AUGUSTUS VAN ORSDALE, OF JASPER, NEW YORK.

IMPROVEMENT IN STEAM-CONDENSERS. i

Specification forming part of Letters Patent No. 81,964, dated September 8,1868.

To all 'whom it may concern:

Be it known that I, AUGUSTUS VAN ORS- DALE, of Jasper, in the county of Steuben and State of New York, have invented certain new and useful Improvements in Exhaust-Steam- Oondensing Heaters, of which the following is a full, clear, and exact description, reference being had to the accompanying drawing, which makes part of this specification, and which represents a section in perspective of my improved heater.

This apparatus is employed to condense steam, and at the same time heat the water or other liquid by which the condensation is effected; and it consists of a suitable casing provided with a series of horizontal plates, suitable conducting pipes, and a steam-delector, combined and arranged to operate as. hereinafter described.

In the accompanying drawing, A represents a vertical chest or heater, into which the exhaust-steam is conducted bythe pipe C. Horizontal plates or partitions a are arranged one above the other in the heater. These plates do not extend the whole length of the heater, thus presenting a small rectangular opening at one end, for the full width thereof, through which the water passes and drops upon the plate below. The plates are so arranged that the openings will be at opposite ends of the alternate plates, so that the water which drops upon one of them will be obliged to pass over its Whole length before it can iind exit to the next. The exhaust-pipe (l enters the heater between the first and second plates from the bottom A2, for the purpose of preventing it from escaping through the water-discharge pipe B attached to the bottom. The steam escaping from the exhaust-pipe C strikes against a curved deflector, D, placed opposite its mouth, for the purpose of further counteracting any tendency to escape through the water-discharge pipe.

Cold water or other liquid is admitted to the heater by the supply-pipe B, inserted in its top A1, and, falling upon the upper plate, passes slowly over its entire surface, and drops upon the plate below, and so on through the heater, escaping, together with the condensed steam, through the pipe B. The steam, in its passage upward through the heater, strikes against the lower side of the plates, and is condensed by the cold water which is constantly passing over them, thereby obviating the objectionable noise caused by the exhaust, and elevating to a considerable degree the temperature of the feed-water. An air-vent, A, is inserted in the top of the heater, for the escape of air, through which any steam which may not be condensed will also find exit; but it is found in practice that the steam is thoroughly condensed before it has passed completely through the heater.

Having thus fully described my invention, what I claim therein as new, and desire to secure by Letters Patent, is-

The combination of the exhaust-pipe O and deector D with the plates a a, heater A, and pipes B B', arranged and operating substantially as described.

To the above specification of my exhauststeam-condensing heater I have signed my hand this 16th day of May, A. D. 1868T AUGUsrUs VAN onsDALE.
